sidebars on individual post pages

hi. I'm trying to find a good way to display certain sidebars on post pages that I have categories for.

I'm not having much luck. I'm trying to use a WP Conditional plugin and it kinda works but its not liking my post categories stuff and just displays everything.

Do you know a good way to do something like that I am describing?
